Palm Beach Gardens Police said Officer Nouman Raja, 38, spotted what he thought was an abandoned car and parked just behind Corey Jones early Sunday. That's when a confrontation happened between the men that resulted in Raja fatally shooting Jones, police said.

There may be relevant video footage in the Corey Jones police shooting that authorities haven't yet disclosed, according to the lawyer representing the slain man's family.

Benjamin Crump, the high-profile civil rights attorney retained by Jones' family, for the first time Wednesday addressed Jones' death on national TV, urging authorities to immediately answer pertinent questions surrounding the death.

Police have said there is no body- or dashboard-camera video that shows Palm Beach Gardens Police Officer Nouman Raja opening fire on Jones, a 31-year-old Boynton Beach man. However, the shooting happened early Sunday off the southbound exit ramp of Interstate 95 at PGA Boulevard, a major thoroughfare.

"What we do know is that this street was surrounded by businesses with surveillance video. There was a street light that had video cameras on it," Crump told CNN's "New Day" on Wednesday. "If the police have video cameras with information, don't hide it from the family. Don't hide it from the community."

The killing of the popular church drummer early Sunday in Palm Beach Gardens was among the latest cases nationally of a young black man who was shot dead by a police officer, sparking a public outcry and helping thrust the case into the national spotlight.

But what happens when two good guys have guns? What happens when one decent person...

"We don't know how many times he was shot," Crump said. "We don't know whether he was shot in the back."

Crump's call for authorities to release any video came as outrage over the shooting reached the state Capitol on Wednesday, with members of the Black Legislative Caucus calling for an independent review of Jones' death.

They also called for legislation that would put safeguards in place for future incidents, including mandatory body cameras for law-enforcement officers, dashboard cameras for police vehicles and automatic, independent reviews of all police-related shootings.

"This has to stop," state Rep. Bobby Powell, D-Riviera Beach, said. "There is no evidence that we have seen that indicates this man was a troublemaker. He doesn't have a record. My community is frustrated, and rightfully so."

Florida Gov. Rick Scott offered the Florida Department of Law Enforcement's help with the investigation.

At issue in the shooting is whether it was the result of Jones and the officer misidentifying each other.

Raja was on duty about 3:15 a.m. Sunday as part of a detail related to a string of burglaries in the city, when the officer approached to investigate Jones' broken-down Hyundai Santa Fe.

Raja, 38, spotted what he thought was an abandoned car and parked just behind Jones, police said.

When the officer exited his vehicle, he was suddenly confronted by Jones, police said. Police said Jones was in possession of a firearm when he confronted Raja, prompting Raja to open fire.

"Apparently, this plainclothes police officer in an unmarked van at 3 a.m. in the morning approaches him," Crump said. "He doesn't know if this is a police officer or not. His family believes he went to his grave not knowing who this person was."

What Jones "needed from police was a helping hand and all he got was bullets," Crump said.

Jones' gun, which according to police Jones purchased three days before the shooting, was recovered from the scene, police said. A photo released by police of Jones' firearm showed it was a semiautomatic.

Jones had bought the handgun to protect himself from any potential danger, Crump said. But there was nothing in Jones' character or history to suggest he ever would open fire on an officer, he said.

"His family, his brother, told me that [when] he went to get the gun, he wanted to make sure it was done legally," Crump said. "He made sure he had a concealed weapons permit. He was within his legal rights as an American citizen to have a gun for protection."

On Wednesday, Gov. Scott consulted with the Palm Beach County Sheriff's Office and Palm Beach County State Attorney's Office, another agency investigating Jones' death, before announcing if the FDLE would offer assistance.

State Attorney Dave Aronberg said his agency has a strong working relationship with FDLE, one in which the two agencies routinely exchange information. In response to the governor's offer, the prosecutor's office has begun communicating with FDLE about the case, Aronberg said.

"We intend to fulfill our responsibilities of fairness and transparency under the law and to the community," Aronberg said.

In an abruptly announced news conference Tuesday, Palm Beach Gardens police offered few new details, insisting that the Palm Beach Sheriff's Office needed time to conduct a thorough review.

Among the records Palm Beach Gardens police said they weren't publicly releasing were any potential 911 calls, reports, video of the scene and investigation, photos, recorded interviews, or radio transmissions. The agency said it was withholding such key information at the behest of the Sheriff's Office "to maintain the integrity of the investigation."

Crump said the little information that police have offered indicated that Officer Raja "did not call this in on his regular channel" to report his encounter with Jones.

"He should have called for backup. He should have told somebody he was going to approach this vehicle," Crump said.

Bob Jarvis, a law professor at Nova Southeastern University not involved in the case, similarly questioned whether Raja could have waited for backup police in uniform to arrive.

"If you are driving along and suddenly an unmarked car is waving to pull you over, you go, 'Is this real?'" Jarvis said. "Cops always say, 'If you have any doubts, you should keep driving to the nearest police station.'"

No one may ever know for certain whether Jones thought someone was approaching to rob or mug him when the officer showed up, Jarvis said. Danger can loom large when a person doesn't realize it's an officer approaching, he said.

As Raja approached Jones, it was about 3 a.m. and possibly dark, Jarvis said. Had Raja been in uniform, the encounter may have ended differently, he said.

"I can't imagine why Raja, as a plainclothes cop, would stop to look at an abandoned car," Jarvis said. "He would call a marked unit."

As Palm Beach Gardens Police Chief Stephen Stepp wrapped up Tuesday's news conference, he declined to address many questions, including any department policy that would have figured into Raja's actions early Sunday.

Jones in 2007 had faced a firearm-related case, but charges stemming from it were dropped.

He was arrested on the charge of having an unlawful concealed carry firearm in Miami Beach, after an officer stopped the vehicle Jones was riding in because the windows were tinted too dark. When the officer went up to the car to speak to the driver of the vehicle, he said he saw a revolver on the floor next to Jones. The gun did not belong to Jones, but a friend, records show.

Charges were dropped in 2009 after Jones completed a program that offers people with no prior record the chance to avoid having charges filed against them. The gun was returned to Jones' friend.

In response to Jones' death, a peaceful protest has been scheduled at 10 a.m. Thursday outside of the Palm Beach Gardens Police Department.

The president and CEO of the Urban League of Palm Beach County, Patrick Franklin, on Wednesday asked for a "thorough and independent investigation that brings clarity and light to all the details surrounding the untimely death of Corey Jones."

"It is our hope that the investigation is both transparent and expedient in order to bring peace to the family and begin the healing process for our community," Franklin said. "During this time, we ask that the community remain peaceful and offer their prayers and support to Corey's family."

Franklin said Thursday's protest will be aimed at expressing "discontent with a national issue of the slaying of young black males either through police-involved shootings or black-on-black crime," Franklin said.

He wants the protest to remain peaceful and doesn't want the unrest that happened in Ferguson, Mo., to happen in Palm Beach Gardens. Violent protests ripped through Ferguson last year after Michael Brown, an unarmed black 18-year-old man, was shot and killed by a white Ferguson officer.

"No one wants to see unrest or their community destroyed," Franklin said. "We don't want to see that in Palm Beach County."

A strong collaboration by the Urban League with local law enforcement, community leaders and others should help create a dialogue and ensure the event remains peaceful, he said.

On Wednesday night, members of Jones' church sang songs and said prayers for Jones at their weekly Bible-study session. Jones normally played the drums in the church band, congregants said, but on Wednesday night a cousin played the drums.

Allayshia Fordham said Jones, her cousin, was a funny, kind soul who loved playing drums. She and her family said they doubt Jones knew Raja was a police officer.

"It's just hard to believe. He worked for the city, he worked with police officers every day. He knew protocol," she said. "For him to respond in a negative manner — I wasn't there, but I would call that absurd."
